The problems people see with the studs pulling out are from overheating the M54 block (water pump failure) not from too much power.

I was on the phone with a guy yesterday for nearly an hour discussing this topic....learned a lot about his engine program, and was able to share a bit of my experience. Sad story though...engine did overheat and he's now looking for a new block.

I thought that was the issue(overheating), this is what vac says ;

Aluminum Block Engines Use Raceware Head Stud Kits and must betime serted for proper installation. Inquire about our Time Sert kit or our in house proprietary time serting service.

I guess that's just as a safety ?

Dunno how much thread engagement there is but with a timesert you only get 25mm(longest i found)
